PSYC 1101 Lecture Notes - Lecture 6: Absolute Threshold, Neural Adaptation, Cochlea
Document Summary
Perception: awareness of elements of environment through physical sensation. Becoming aware of something would be your perception. Making sense of complexity: our sensory and perceptual process work together to see complex images. Bottom- up processing: make sense of photos through sensing lines, angles, and colors. Top- down processing: we consciously look into the depth of a picture and notice the little details. Transmission: delivering the neural impulses to the brain. Thresholds: some stimulus energy we do or do not detect the obvious: absolute threshold: minimum stimulation needed to detect something is 50, subliminal threshold: is just below our threshold. Ex: air conditioning, background music, people breathing, pencils writing on a piece of paper, etc. Sensory adaptation: nerve cells begin to stop picking up things when we do it often. Perceptual organization: mental pre-disposition to perceive one thing and not another, basically you perceive how you are told over and over again.
